Is this a good idea that should be implemented in Forumotion?

So, basically, when you create a forum or catagory, you have the option to put a password on it, so if you would like to have a "basic" membership and a "advanced" or "premium" area, where when you upgrade to the premium level, the Admin's email you the password to get in the special forums.

And when non-members try to go to it, it will say a custom block of text; example: "Sorry! You are not a premuim member, and you cannot enter this forum. Click here to become a premuim member and get a ton of new things!"

I would like this, but i already can do it.I did on my forum.I just make it set to people who are a certain rank, and once they reach that rank, they can post in the forum, and i add them to a hidden group, that allows any person in that group, to post in that forum....only problem is that it's not auto-matic.
